Uptime wasn't very high (a couple of days only) and I don't know which circumstance causes it to get amnesic by ncr timeouts. It has two ncr PCI controllers (cheapo) and today I swapped them against SC200 (ASUS). Still not sure if this will cure it. The symptom is as follows: ncr1: SCSI phase error fixup: CCB already queued (0xf0d55200) ncr1: timeout f0d55200 (skip) ncr1: timeout f0d55200 (skip) ncr1: timeout f0d55200 (skip) ncr1: timeout f0d55200 (skip) ncr1: timeout f0d55200 (skip) ncr1: timeout f0d55200 (skip) The system is dead in this situation, i.e. cannot access it's disks. The two ncr controllers form a CCD devices (two quantum 3 GB disks = 6GB) This ccd device is NFS exported to ftp.de.freebsd.org and I suspect that it happens when ftp.de.freebsd.org runs it's nightly ls -lR >ls-lR file which might also be a NFS stress test and maybe it's the combination of NFS, CCD and the two controllers. Or might it be just a hard drive problem? Well, the hardware was brand new when I bought it 5 months ago. So at present I put my hope in the maybe somewhat better (ASUS) controllers. But maybe Stefan could comment this also. -- Chris Christoph P. U. Kukulies kuku@gil.physik.rwth-aachen.de
